Speccaton of Letters Patent.

Patented Dec. 17, 1907. i

To all whom it may concern: i

Be it known that l, WiLLiAM Ziicnow, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State of'Visconsin, have invented certain new and useful Improvements inFertilizer- Distributers, of which the following is a specification,reference being had to the accom; panying drawing, forming a partthereof.

This invention relates to that class of fertilizer-distributers whichembodyI a box or body mounted on a wheeled frame, a movwhich thefertilizer is placed,iand a rotary distributing cylinder, against Vwhichthe fertilizer is slowly fed by the movement of the bottom .and by whichrearwardly from nthe machine.

he objects of this invention are to im' prove the construction of themovable bottom and the mechanism by which the feed movement is impartedto it; to provide a ysimple and convenient mechanism for returning thebottoni to its initial position by power derived from the rear axle whenthe load has been distributed; to provide an iinroved clutch mechanismthat is automatically operated to disconnect the motive power from-theoperative parts when the saine have reached predetermined positions; toprovide an improved form of comb to assist iii disintegrating thefertilizer, and to provide means whereby the comb is given a vibratingmovement longitudinally relative to the axis of the distributingcylinder; to provide an improved form of track for the movable bottom,and an improved construction of the box and distributing cylinderwhereby the tendency of the fertilizer to clog at the ends of thecylinder is avoided..

The same reference numerals represent similar (parts throughout theseveral views.

1 an 2 are the right and left-hand sills respectively of the body frame,3 and 4 are front and rear cross sills, and 5, 6 and 7 representintermediate cross-sills that are secured to the side sills. i

Secured to the side project upward and serve to support the sides l) ofthe body. The body is mounted upon a front axlelO, and a rea-i' axle 11,the latter being caused to rotate in a forward direction by the carryingwheels 12 and the usual backing ratchet mechanism 13 connectedtherewith. rl`he rear axle is journaled in side casti gs or brackets 14and 15 that are secured to the sills 1 and 2 respectively.

16 is a flexible bottom consists of bars hinge jointed together by meansof links 17 at their ends and other links 18 at their middle portion.The links 17 have rollers 19 that rest upon metal tracks 2()`V securedto the upper side of the-side sills, and the sides of the body at theirbottom edges are nearly in contact with them and operate to hold thebottom in proper aline ment; and 21 are guard strips secured to theinner surface of the sides for the purpose of l shielding the connectinglinks. The bars are l supported attheir middle portions by means l ofrollers 22 journaled in' the links 18 and resting upon a metal track 23,supported by sills are straps 8, that for the body, which,

25, 26 and 2 7. are details of the mechanism in eitherdirectionqthereby. The castings 24 and 25 are-provided with annular rims29 that partially surround the sprocket wheels 3l and 32 connectedbybeater bars 33 having Y to prevent clogging of the cylinder; but suchthe cylinder teeth attached thereto. y y

In operating machines of this class, as heretofore constructed, 'troublehas been met with by reason of the fertilizer being crowded between thecylinder head and the inner sides of the box shields have been employedat the juncture of the heads and sides of the box means have not provedentirely effective, and to remove the evil'l have made `the cylin- `derlonger, so that the outer surface of the head is beyond the innersurface of the body sides, as shown in Fig. 2 1

.In front of and above the distributing cylinder is mounted a comb bar34 having comb teeth 35 independently and. yieldingly mounted thereon,the bar is preferably tubular and the teeth have forked arms embracingit. Clips 36 are secured to the bar between the arms and have lipportionsA 37 that engage with central projections on the teeth inamanner to limit their downward movement, and a coiled spring 38 operatesbetween the clip and tooth to yieldingly hold the latter in `itsdownward position. .The comb teeth p free swinging links 39 Vand 40 thave their points in' close proximity with the teethof the distributingrcylinder and operate to hold back masses of the fertilizer and assistin'a better distribution' of the same. Thev upper ends of l at aresupported .by straps 41 j and 42, respectively,

eomb bar'is-mounted at the upon opposite sides of the body, the linksbev ing free to swing laterally and slide longitudinally a liinit'eddistance toallow the 'comb bar to rise under unduepressure and tonormally float upon the moving load.

Motion is communicated 'to the various parts in the following manner:The rear axle 11 is causedto rotate in/'a forward direction by means ofthe carrying wheels, as `before stated. `Adjacent the hub of the wheel,at the left-hand side ofthe machine, between said hub and the sidecasting 15,` there is se'- cured to the axle a sleeve 43having anannular flange 44 provided with clutch-teeth 45 at its inner end.Journaled upon the sleeve is a main driving sprocket Wheel 46, providedwith clutch teeth 47 adapted to .engage with the clutch teeth upon theannular flange of the sleeve in a manner to cause thesprocket wheel torevolve with the sleeve when so engaged. The sprocket wheel has acylindrical portion outside its bearing upon the sleeve,

and a disk 48 is loosely fitted to slide therein. The, disk is providedwith notches 49 in its periphery that engage with ribs 50 on the innersurface of the cylinder in a manner to cause the disk to rotate with'the .sprocket wheel.. The sprocket wheel` is .adapted to movelongitudinally along the 'sleeve sufficient to allow the two sets ofclutch teeth toI become disengaged, and coiled springs 51 operatebetween the disk and Wheel to yieldingly hold the clutch' parts inengagement. Secured to the axle, upon the opposi-te side of the journalbearing forming part of side casting 15, is a sleeve 52 provided. withclutch erative between.` the sproc iet Wheel 53 and the collar or washer55 that is held against longitudinal movement by a pin through the axlein the common way to normally hold the clutch in engagement. Acylindrical shell 56 surrounds the sleeve 52 having a bearing at one endthereon and at its opposite end on the journal bearing of part 15 and.bearing against the rim of the sprocket wheel 53. A clutch shipping ring57 is rotatably mounted on'the -journal bearing ofthe part 15 betweenthe shell 56 and the web portion of said part l15. The shippingring isadapted to move longitudinally upon the journal bearing, and 58 and 59are opposing annular cam surfaces on the ring and part 15, respectively,that are adapt-ed, when the ring is rotated in one directio'n7 to movethe ring longitudinally/ran a manner to pressfagainst the shell 56 andcause the sprocket wheel 53 to be disengaged from the Yclutch sleeve 52.su plemental clutch shipping ring 60 is rctatablly mounted on theopposite side of the side casting 15, having laterally projecting stems61 passing .through slots 62 in said casting that are concentric withthe axle, said .stems engaging withJ shipping ring 57 in a manner to bemoved thereby and cause the,y ring 6() to be simultaneously rotated withthe ring 57.

The ring 60 bears against the inner surface of the sprocket wheel 46,and 63 and 64are opposing annular cam surfaces on the ring 60 and part145, respectively, that are adapted to separate the clutch teeth of thesprocket @wheel from those of the sleeve 43 when the 'shipping' ring isrotated in one direction. The cam surfaces on the respective parts arearranged in a manner to operate to hold the small sprocket wheelunclutched from its driving member during the time the large one isengaged with its'(.lrivi1ig member, and vice versa, or they will operateto holdboth the sprocket wheels unclutched, accordingto *he position o1"the rotatable clutch shipping rings and the slots 62 are madesufficiently 130 -svasas long to allow for the necessary movement of and6l) is a spur pinion secured to the shaft of the distributing cylinderand meshing with the teeth on the spur gear part of the wheel 67 in amanner to be driven thereby. The spur pinion 69 is'provided with alaterally projecting hub portion 70 that is eccentric with its axis andhaving its end surface at an angle with itsl axial line and providedwith a boss 71 concentric with the vhub and having its end surfaceparallel with that of the hub. An arm 72 is mounted upon the boss, and awasher 73, provided with a depression which engages the pint-le 7 4 onthe boss, is secured to the shaft outside the armby means'of the nut, asshown in Fig. 31. The angular surface of the hub operates in therevolution of the cylinder to vibrate the arm 7L, which, at its outerend, is connected with the comb bar IH and produces a vibrating'movementof the bar longitudinally relative to the distributing cylinder. T hecomb bar swings with the arm 72 upon one side, and with the link 75 uponthe opposite side of the machine. The vibrating movement imparted to thecomb bar is an important feature of this invention and assists`materially in disintegrating the mass of fertilizer as it is deliveredto the distributing cylinder. The movable bottom has secured to itsforward end a follower 76, comprising a substantially vertical upperportion 7,7, and al downward and rearward inclined portion 78, for thepurpose of delivering the contents of the body to the distributingcylinder in a better manner than heretofore. f

Connected with the side castings 24 and 2.5, and forming a continuationof the flanges 2Q, are angle bars 79 and S0, respectively, that extenddownward and forward below the axle, n here they are secured to the sidecastings 14 and 15 and perform the double function of braces for saidcastings 'and a track for the movable bottom. The bars extend fora ardof the axle substantially parallel nith the horizont-al plane of theside sills and are connected at their forward ends with upturuedcircular portions S1 connected *with horizontal return portions S2 thatoperate to return a portion of the bottom tot. ard the rear for thepurpose of preventing it from coming in contact `with the front'r'.zheels as they are turned under the body during a turning movementof the machine.

The flexible bottom is caused to' move rearward by means of theinternal,ratchet the same relative speed at all times.

Wheel 83 secured to the end of the shaft 26 at the right-hand side ofthe machine,f that is actuated by means of spring pressed pawls 84,pivotally mounted upon a pawl carrying lever 85 that is rotatablymounted upon'the shaft 26 between the ratchet wheel and the part 24. Thepawl carrying .lever V85 is caused to vibrate about its bearing by meansof the two-part telescoping pitman 86, conn ecting it withan eccentricS7 secured to the end of the distributing cylinder shaft. The throw ofthe eccentric is positive, and if it was connected with the pawlcarrying lever by means of an unyielding pitman, it would actuate thelever and the lratchet wheel through the same distance at each strokeand thereby move the flexible bottom with 1t is desirable in this classof .machines to provide means whereby the speed ofthe movable bottom maybe regulated relative to the vspeed of the distributing cylinder, and tosecure that result is one object of this invention. The pawl carryinglever is moved toward the distributing cylinder by a positive 'pullingaction of the pitman, and is moved in the opposite direction by' theyielding force of the coiled spring 8S surrounding the pitman andoperative between opposing shoulders on the two parts of the pitman.When the pawl carrying lever is adjusted to the full limit away from thecylinder, .the pit-man operates with its full length to vibrate the arm;when the arm is adjusted Atoward the cylinder, the part S9 of thepitinanwill slide through the part-90 until stopped by the head formed upon thepart 89 coming in contact with the part-90, and the measure of theeffective pullthereof will be governed by the amount of free 'movementof one part relative to the other, that is, the lever will only be movedin a direction to turn the ratchet wheel when the pitman exerts apulling force thereon, and as the pawl carrying lever is adjusted to orfrom the cylinder the distance through which that force operates will bedetermined and the speed of the flexible bottom in its rearward movementgoverned accordingly.

Mounted upon the pawl carrying arm, within the rim of the ratchet wheel,is a rotatable ring 91, having laterallyprojecting ear portions 92 thatare adapted to contact with the pawls 84, when the ring is moved in onedirection, in a manner to move the pawls out of operative engagement:with the internal ratchet wheel. lt is desirable in this classof'machines to provide` means for lool;- ing the flexible bottom againstaccidental movement rearward while the machine is being transported andprevent the load from crowding against the cylinder', particularly whenascending a hill. The locliiug means .tween the pawl and lthe part -24being shown 1n' Fig. 27 .f When the machine is in operal tion and movingdown an incline, there is a tendency for 'the bottom, with its load, to.

move forward during the time between the operative action of the pawlcarrying arm and its return, and thus stop the effective feed. Toprevent this there is mountedl upon the stud that carries the springpressed pa vl 93 anumber of gravity pawls 97 olf different lengthsadapted to engage with the teeth of the ratchet wheel and hold it in thedirection of rotation caused by the operative Vpawl vcarrying arm.,During the return movement of the bottom the gravity pawls are renderedinoperative by means of the projecting ear 95 on the ring 91 holdingthem out ofengagement with the ratchet wheel.

The means provided for adjusting the operati've-mechai'iism comprises ahand lever 98 mounted on a rock shaft 99, suitablyT mounted on the frontcross sill 3 of the machine and having the spring pressed detent 100adapted to engage with the ratchet teeth on a sector rack 101. Y Securedto the rock shaft is a depending lever 102. A rock'"haft 103 is rtatably4mounted in the side sills in rear,.of the axle, and secured thereto, isa double armed lever104 that has its lower end yieldingly'*l connectedwith the lever 102 by means of the rod 105', yoke 106 and coiled spring107,`and its upper end yieldinglyconnected with a sliding bar 108suitablyT mounted on the cross bars 4 and 7, by means of the link 109,bracket 110 and coiled spring Inside nof sill 2, and substantially inline With the clutch shipping ring 57, there is secured to the rockshaft 103 a depending lever 112 that is connected with the ring by meansof the link 1 13; and upon the rock shaft, outside the sill 1, issecured a bell crank lever 114 having one arm connected, by means of thelink 115, with the pawl carrying arm 85, and the other arm with thepawl. controlling ring by means of the link 116. Thepawl carrying arm 85has an elongatedvslot that receives the end vof the link 115 for'thepurpose of permitting the operative action of the arm. K

Referring to Figs. 22 and 23, the throw or 'vibration of the pawlcarrying arm depends upon the position to which itis adjusted by themovement of the hand lever 98 and rock shaft 103, and aspreviouslystated, the yielding pitman connection between the eccentricon the cylinder shaft and the pawl carrying arm permits such variablethrow.

The several levers are so proportioned that shown in Fig. 19, having thesprocket wheel 53 engaging with the olutchsleeve 52, and a sprocketchain 117 connects sprocket wheel 53 with sprocket wheel 118 secured tothe shaft 26, and operates to return the movable bottom to its initialposition to receive its load. To automatically arrest the movenient ofthe bottom as it reaches the limit in either direction is the functionof the sliding bar 108. At' its rear'end the bar has a laterally'projecting portion 1'19 that isadapted to engage with a depending lug120 secured to the front bar of the bottom and be moved thereby when thebottom has reached' its rearward limit, and the bar through its linkconnections with the rock shaft 103 operates `the clutch mechanisnrltoarrest the move.-

ment of the operative/parts. When the botl'tom is returned to itsinitial position to receive the load a depending lug 121, similar to lug120, is secured to one of the rear bars of the bottom and contacts withthe bar 108 in a like mamier to arrest the movement of the operativearts. lug 120 is 1n contact with the lateral projecn tion 119 on thesliding bar 108 and would operate to immediately rockthe shaft 103 inits beaings and lthrough its. connections with the feeding meclanism,the rock shaft would operate to gradually reduce its speed. 1t isdesirable that the speed of the movable bottom be unchanged until it hasreached its rear limit, and to insure this the rock shaft is lockedagainst movement at this time by means of the locking lever 1 22pivotally mounted at the front of the machine, on a horizontal pivot andhaving the rearwardly upturned portion 1221 adapted to engage with therear bar of the movable bottom in a manner to cause the lever to rockabout its pivot and having the hook 123 at its forward end adapted toengage with a projecting ear on the depending-lever 102. for the purposeofA preventing the forward movement of the lever 102, and consequentlyholding the rock shaft 103 from. turning. '.lhc spring 111 on the link109 yields and. allows the slide to move under pressure from'the movingbotu tom until thebotton'i reaches its limit rearward, when its rearbar, as shown in dotted lines in Fig. 4, will raise the rear end of thelever 122 and disengago the hook from the ear and spring 111 willinstantly rock the shaft 103 in its bearings to unclutch thc operativemechanism, as before described.

And when the hand lever is moved4 As shown in Fig. 25, the.

Cil"

When the hand lever is moved rearward and before contacting with thehead formed ,its detent is in therear notch of the sector rack inposition to return the bottom, it requires considerablel force todlsengage 1t 5 Jwithout first releasing the detent from the notch, andto enable the automatic means for arresting the movement of the bottomto operate independent of the hand lever is the purpose of the yieldingconnection. of' the link- 105 with the depending lever 102 by meansofthe spring yok'e106.

The various adjustments of lever 98 are shown diagrammatically in Figs.23, 24 .and 25, the dotted linesiin Figs. 24 and 25 representingthepposition ofthe lever when the clutch vmechanism is neutral, as shownin Fig. 20, and the distributing cylinder and movable bottom are atrest. A

When the hand lever is moved forward to the position shown byfulLlinesin Fig. 4, the large sprocket wheel on the rear axle is engaged with itsdriving member of the clutch mechanism and the distributing cylinder isvgiven motion and communicates it tothe ratchet feed mechanism foroperating the flexible bottom which 1n. this position is ad- .justed fora slow speed. To increase its speed the lever is moved further forward.Vhen the lever is moved forward from the position shown in Figs. 4 and23 it does not aect the operativeness of the clutch mechanism, the

slots 62 Aallowing the stems 61 to move freely therein; the cam surfacesthat actuate the clutch parts being provided with flat portionsv thatallow the clutch members to remain at rest during a part of the'rotation of the clutch shipping rings. f Figs 23, 24 and 25 representvarious adjustine-nts of the feed mechanism as the hand lever adjustedforward or rearward. YIn the full line position of the parts, as shownin Fig. 24the hand lever is thrown `to the limit ofV its rearwardmovement and the clutch mechanism -is in the position shown in Fig. 10,and the sprocket wheel 53v is operative to return the movable bottom toits receiving ymsition, and the distributing cylinder and feed mechanismremain inactive. llVhen the hand lever is adjusted Iin a forwarddirection, as shown by full lines in Fig. 23, the clutch mechanism is'in the position shown in Fig. 7, the sprocket Wheel 46 being Y operativeto transmit motion-to the distributing cylinder, and through `itto thefeed mechanism,which latter is almost inactive,

caused by thelink 1-15 holding the pawl carrying arm 85 against theforce of the spring SS and preventing a forwardmovement of its upperend, and consequently the pawls cannot clutch with the ratchet teeth ata distance from the axis of the eccentric 87 suicient to make iteffective to move the ratchet wheel but a lit/tlc owing to thefreemovement of the part, 90 along the part SQ of the pitman thereon. l y

When the lever is adjusted forwand from the last named position, asshown by dotted lin'es in' Fig. 23, the rearward movement of `the link115 allows the arm'85 to vibrate about its axis in a manner to increasethe distance between its upper end and the axis of the eccentric 87, andthe effectivel pull ofthe pitman -is operative to move the ratchet wheelthrough a distance proportionate with the distance through which thehand lever is moved forward.'

The entire mechanism is under full control of the operator, and by meansof a single hand lever having a movement in a fore' and y aft direction.

With the boX filled Iwith the fertilizer to be distributed and the handlever 98 in the position shown by dotted lines in'Fig. 4, the operativeparts will remain at rest, as the clutch members on thel aXle aredisengaged from the sprocket wheels 46 and' 53, as shown in Fig. 20.When the hand lever is moved forward the connecting link 105, connectedwith 'the lever 102, causes the shaft 103 to rock 1n vits bearings bymeans ,of the lever arm 104 secured thereto, and to which the link isconnected. The rocking movement of the shaft causes a movement of theclutch shipping ring 57 in a .direction to allow vthe main sprocketwheel46 to engage with the clutch Y member 43, by means of the lever arm 112,

secured to shaft 103, and the link connection 113. The parts are now `inposition to transmit motion to the distributing cylinder', and thedistributing cylinder transmits motion to the pawl carrying arm 85,which'becomes effective to advance the movable bottom toward thecylinder when adjusted by means of the link connection and lever arm114, which adjustment is caused by a further forwardmovement of the handlever until its detent is in position to engage with the forward seriesof notches in the sector 101. The

notches are so arranged and the associated partsy of the feedmechanismproportioned to give a step by step increase of speed, the increasebeing about one-eighth of an inch for each notch; that is, when theidetent is in the rearmost notch, the feed rearward of the flexiblebottom is about one-eighth ofgan inch for each revolution of thedistributing cylinder, and it increases one-eighth of an inch for eachnotch theA lever is,moved forward. When the bottom has moved rearwarduntil the load has been discharged, its movement is automaticallyarrested and the hand lever returned to its initial position aspreviouslyT described. l

To caus\e the flexible bottom to return to its initial position, theoperator moves the hand leverrearward to the rearmost notch in thesector rack, and the link 105'transmits until'the clutch ring 57 is soadjusted as `to allow sprocket Wheel 53 to engage with the y clutchmember 52, and then, by means of the chain 117, motion is directlycommunicated from the axle to the shaft 26 to move it m a direction toreturn the flexible bottom to its i initial position to receive a load.
